Title: Dimension measuring gauge
IPC: G01B11/04
Filed: 1960-04-21
Abstract: 913,049. Photo-electric gauging. GENERAL ELECTRIC CO. April 20, 1960 [May 4, 1959], No. 14007/60. Class 40 (3). A gauging device for measuring the dimension of an object comprises a scanning head including a rotatable member with a plurality of equi-spaced portholes disposed in a line around its periphery and a plurality of counter marks formed adjacent each porthole for providing an indication of the dimension of an object viewed through the portholes. The scanning head 11, Figs. 4, 5, is formed by a drum member having eight portholes 13 each provided with a lens 16 and effectively traversing a length indicated by A, B, C, Fig. 1, spanning or including the object 12 which may be a white-hot slab of steel and from which light is passed to a photo-transistor 17 mounted near the axis 21 of the drum. The plane end-surface 22 of the drum is provided with eight circularly arranged and equally spaced holes 23 which allow light to pass from sources 27, 28, 29 to photo transistors 24, 25, 26 disposed within the drum and positioned so that they are actuated in succession as the lines 13a, 13b, 13c from the axis of the drum through the centre of a porthole 13, are directed to the points A, B, C respectively on the member carrying the object 12. Screens 33 provided with counter marks disposed axially of the line of portholes 13 and lying between each pair of portholes are associated with a light source 37 anda photo-transistor 36. The marks are arranged on the screens 36 to allow for the non-linearity of the scan and for different thicknesses of the objects 12, and the scanning head 36, 37 can be moved axially of the drum by a shaft 38 actuated by a servomotor to allow for different conditions. Pulses from the transistors 24, 25, 26 control an " inzone " detector 41, Fig. 7, passing a pulse to a read-out gate 42 providing an input to an " AND " gate 77. A pulse from the photo transistor 17 corresponding to the length of the object 12 provides a second input to the gate 77 so that pulses from the photo transistor 36 associated with the marker screen can pass to a binary counter 89 and thence to a circuit 123 for conversion to a decimal basis, and display on a screen device 124. The added result of eight determinations is displayed and this total may, if desired, be divided automatically to indicate the measured length of the object 12. Each pulse from the detector 41 in response to a pulse from the transistor 26 effects illumination of the display device 124, and after eight of these pulses the counter 89 is reset to zero.

Abstract: 461,104. Mould materials; moulding processes. KROSTA, V. May 22, 1936, Nos. 14457, 14458, and 14459. Convention dates, May 25, 1935, Feb. 20, 1936, and Feb. 20, 1936. [Class 83 (i)] In order to compensate for the shrinkage, on cooling, of castings of metals of the iron group and alloys thereof with metals of the third to the sixth group of the Periodic System and melting at 1000 to 1600‹ C. the mould is made entirely or chiefly of #-quartz and is heated, before pouring, so that the quartz is converted into tridymite or cristobalite thus causing the mould to expand. The amount of expansion can be varied according to the size of grain and origin of the quartz used, i.e. quartzite, kieselguhr, precipitated silica; so called silicious materials &c. or by adding catalysts, such as tungsten trioxide or phosphates, borates, silicofluorides, or already formed tridymite or cristobalite. The silica may be mixed with binders such as quartz ground to colloidal form, water glass which also acts as a catalyst, glue, dextrin and mastic or colophony dissolved in carbon tetrachloride. The moulds are heated in muffles of silicon-carbide. To prevent any chemical action between the mould and the cast metal or oxide thereon, substances of the same composition as those which might be formed by such action or substances which furnish the same reaction product on heating, are added to the mould material or the mould is not heated so highly, e.g. an alloy containing 70 per cent of nickel and 30 of chromium is cast in a mould at 700-800‹ C.

Title: Improvements in electrically controlled lifts or the like
IPC: B66B1/52
Filed: 1924-06-17
Abstract: 220,932. Waygood-Otis, Ltd., (Assignees of Dunn, E. L.). Aug. 23, 1923, [Convention date]. Electric plant. - The cage is brought to a level stop at any desired landing when the cage switch is centred, by means of two series of contacts operated by the travel of the cage, one series establishing levelling zones for the several landings, while the other series determines the direction of the correcting movement in those zones. The cage rotates a shaft 1 by means of a metal tape 40 wound on a drum 4 on the shaft; a second tape 41 carries the counterweight 44. The shaft 1 has a screwed part carrying a nut 8 making a circuit between a bar 11 and a series of insulated contacts 12 - - 16 corresponding to the various landings. A drum 18 on the shaft 1 has two conducting segments 21, 22 separated by an insulating strip 19, and connected respectively to the coils of the up and down reversing switches U, D of the motor. The segments rotate past fixed brushes 29 - - 33 each of which is in series with one of the landing contacts 12 - - 16. When the cage switch 56 is centred after being, say, in the hoisting position, the motor is first slowed down by the opening of a fast-speed switch, and the main circuit through the coil of the up reversing switch U is broken through a contact 60. If the cage is in the levelling zone a circuit is still made through the coil of the switch U through, say, contact 13, fixed brush 30, segment 21 and lead 74, so that the cage is still hoisted at slow speed. When the landing is reached the insulating strip 19 comes under the brush 30 and breaks the coil circuit so that the motor stops with the cage level with the landing. If, however, the cage runs past the landing the other segment 22 comes under the brush 30, the circuit of the down reversing switch D is made and the motor is started in the reverse direction to bring the cage back to the landing.

Title: Improvements in or relating to devices for determining a time integral of an electric current
IPC: G06G7/184
Filed: 1946-05-15
Abstract: 612,345. Energy and quantity meters. PHILIPS LAMPS, Ltd. May 15, 1946, No. 14701. Convention date, March 4, 1942. [Class 37] The time integral of a current (i.e. quantity) is determined by measuring the voltage of a condenser 4, Fig. 1, charged by the voltage drop across a resistance 3 in the main circuit 1, 2, the resistance 3 being of low value compared to the total resistance in the main circuit. The invention is shown applied to measuring X-ray dosage. Preferably a high resistance 5 is in series with condenser 4. In a modification, a triode valve is in series with condenser 4, Fig. 2 (not shown), to eliminate the effect on charging by the back E.M.F. of the condenser. In a further modification, the current through resistance 3, Fig. 3, determines the voltage of tapping 7 which determines the conductivity of screen grid valve 10 and the charging of condenser 4 from a source 8, 9; a relay is operated when the condenser voltage reaches a predetermined level; negative feedback over resistance 14 assists to make the current charging condenser 4 proportional to the current in resistance 3.

Abstract: 1,056,482. Detecting flaws electrically. REPUBLIC STEEL CORPORATION. April 9, 1964 [April 9, 1963], No.14758/64. Heading G1N. [Also in Division H3] Defects, such as seams, in a moving metal bar 15, Fig. 1 (not shown), are detected by a detector 12, the output signals of which are fed in cyclic succession to different channels 215, 216, 217, 218, Fig. 3 (not shown), in a control circuit 13, each channel containing a pulsedelaying circuit 221, &c. and operating a common defect marker in the form of a carbide cutter 21 when a defect has travelled from the detector to the marker. The bar rotates relatively to the detector, which thus describes a helical path along the bar, and the spacing between the detector and the marker is such that when a detected defect has moved through a complete revolution, it is exactly adjacent the marker when the delayed pulse operates the marker. Any further defects detected during this revolution are similarly marked when the marker is operated by corresponding pulses stored in other channels. A dekatron 207, Figs. 3 and 4 (not shown), is used to select the channels, and the output pulses drive a single monostable multivibrator 235. An eddy current type detector is used, and the carbide cutter 21 which is driven by a motor 22, Fig. 2 (not shown), is biased pneumatically into the marking position against a spring 25, which holds it in a normally retracted position. The multivibrator 235, operates a relay 237, which operates a solenoid air valve 14, controlling the marker.

Title: Actuating mechanism for a powder or like packeting machine
Inventor: GWILT CHARLES
IPC: B65B65/02
Filed: 1952-06-12
Abstract: 719,263. Ratchet gearing. SOUTHALL & SMITH, Ltd. June 10, 1953 [June 12 1952], No. 14815/52. Class 80 (3) An actuating mechanism for a powder or like packeting machine of the kind for delivering powder &c. into bags &c. in measured quantities the size of which is determined by how much a worm is turned in a nozzle extending from a supply hopper, comprises the combination of a driving clutch member g, a coaxial driven clutch member h, an interlocking member in the form of an oscillatory key j carried by the driving member and engageable with any one of a series of adjacent recesses l around the periphery of the driven member, a stationary cam m for actuating the key, a ratchet q on the driven member, a pawl v adapted to actuate the ratchet for resetting the driven member at the end of each rotation of the said member, a rotary cam u for actuating the pawl, and a unidirectional clutch x between the driven member and the worm. The driving member g is rotated by a chain or belt, and the key j which it carries is fast with an arm k carring a roller n which runs round the stationary cam m. The pawl v is carried by a bellcrank lever r pivoted to the casing and spring- urged into engagement with the ratchet q, the outer end of the bellcrank lever carrying a roller t co-operating with the rotating cam u which is fast with the driving member g. On rotation of the driving member, the key j is turned by the interaction of the roller n and cam m to engage with the recesses l in the driven member, which is then rotated until the shape of cam m moves the roller n to turn the key and break the driving connection; the cam u on the driving member then actuates the bellcrank lever and pawl v to rotate the driven member h backwards to a position where one of the recesses l is correctly aligned for reception of the key at the commencement of the next cycle. The backward rotation of the driven member does not rotate the worm in the packeting machine because of. the interposition of the freewheel x between it and the worm-driving shaft f. The cam m is of an adjustable profile, so that the quantity of powder &c. discharged by the worm during each cycle can be varied.
